I live in one of the few wards that will hold a runoff election for the Chicago City Council on Tuesday. These runoffs will cost the city tens of thousands of dollars.

We should follow the lead of London and Dublin and use instant runoff voting, where voters get to pick their favorite candidate and their second-choice candidate at the same time.

Instead of holding a separate runoff election, we would just count the second-choice votes of the people who voted for an eliminated candidate. Why pay for two elections when we can get the job done inone?
